"The remote host is affected by the vulnerability described in GLSA-200409-12
(ImageMagick, imlib, imlib2: BMP decoding buffer overflows)

    Due to improper bounds checking, ImageMagick and imlib are vulnerable to a
    buffer overflow when decoding runlength-encoded bitmaps. This bug can be
    exploited using a specially crafted BMP image and could potentially allow
    remote code execution when this image is decoded by the user.
  
Impact :

    A specially crafted runlength-encoded BMP could lead ImageMagick and imlib
    to crash or potentially execute arbitrary code.
  
Workaround :

    There is no known workaround at this time."
